Going to pull the p.o.s xe274 out of my 347. Makes good hp but is way to noisy. What are you guys running in your 347's that don't make the dreaded clatter. Oh ya, don't suggest a custom cam eather, there are plenty of cams out there off the shelf for this combo.
347, 9.5 to 1
Performer intake
Aluminum 190 heads
all the usual goodies
ran a 12.62 with the xe cam, just hate driving the noisy f%&&

Any modern cam with quick ramp speeds is going to have a little noise. My bro-in-law has the xe274 in his 331 and its not bad at all. I also run the xe266hr in my 5.0 Capri without much noise.

What kind of rockers are you using?

[Stanger90]

Ya friend has the xe266, with less noise too. Might be an option, less duration.

[horsepowerjunkie]

Check out the Anderson Ford Motorsport cams. They are supposed to be the shitz!

[69fastback]

Advertised duration numbers have nothing to do with the noise. Why does it matter if it chatters? It's just the nature of the beast. I have a custom Bullet cam in mine, and it chatters like crazy. It's just the way it is.

How much preload do you have it set at? Have you tried more? Have you tried setting it with the engine running?



So you think there are plenty of cams that are made for your setup, yet you only list about 15% of the equation for picking out a cam. you may want to re evaluate.

[Stanger90]

I've tried everything from an 1/8 to 1 turn, nothing seems to help. Just under half seems best. I just got a set of comp lifters that I'm going to try, probably just another waste of gaskets and time.
Really what is the point of running a hyd lifter, might as well put a solid in if I want to hear the clatter.
Did you have a cam in your car that didn't make any clatter? That's what I was looking for..
Oh duration #'s and lobe lsa do have alot to do with this because it contributes to the steep ramp rates that must be making the noise. They're trying to do to much in a short time.

[69fastback]

But an advertised duration doesn't show ramp rates. That's what I was getting at.

The idea of running a hydraulic, instead of a solid, based on noise, is a little flawed. I run a hydraulic based for it's low maintenance, and forgiveness in a street car. A solid will require occasional lashing, and extended idle time will cause the lifters to fail, due to high spring pressures, and the amount of oil they receive at idle. Typically, you'll have to replace the springs once a year. Noise is just a bi product.



Buy the blue Trick Flow Gaskets and you won't be ruining any, and you won't have any leaks. They're like $20. Mine have been on and off probably 100 times.

how the hell do u hear cam noises over ur engine and or exhaust?

My exhaust isn't exactly quiet, and the engine sounds like a sewing machine going down the road.

i also have the XE cam...its loud..

[Stanger90]

Listen guys, I don't care if you like the clatter from the xe series camshafts comp puts out, I don't!! The reason why I started this thread was to find out if there is something out there that doesn't make noise that someone likes in there engine. If you don't have a cam to suggest don't chime in to defend your noisy xe cam.

[69fastback]

You want a stock acting/ sounding engine, then put stock stuff in it. Anytime you go performance, there will be compromise. It's not that I like the chatter. It's just that I understand, that's just the way it is. I'll sell you a stock 351W cam for $20.

And also, you referred to a good cam as a pos, on a public forum, because of a sound that's perfectly normal. People that don't know any better could be reading this, and be deterred from buying a good cam, and they need to know that there's nothing wrong with it.

[Stanger90]

On the same note, I think that people need to know that this cam will make noise so buyer beware. There are many threads of people complaining about it, ford and chevy. BTW I've had this cam for 2 years and it definately gets louder over time so it's beating up on something the valvetrain.
I said it makes good hp, but the pos is a damn sewing machine and not what I want. So I thought I'd ask my fellow mustangers what they like that don't make noise and all I get is you telling me to deal with it. If you like it great, but keep it out of this thread because it's not why it was intended.

Op is high strung. I heard b cams are the quiet...

Lol....That's what I was going to say. Sounds like it likely has Procomp heads on it anyways, so it doesn't really matter what cam you put in it. I'd be a whole lot more worried about those heads dropping a valve seat into the engine, than I would some cam noise. My billet core, custom cam from Bullet makes more noise than my old XE cam ever thought about making.

Look into an E cam. Stroker with some Procomps, and a letters cam should haul some ass.

[fogged306]

^^ This

What heads do you have? If they're cheap heads then there's a very good chance that the rockers aren't lined up very well and this will cause a LOT of noise. Did you measure pushrod length? How thick was the witness mark? How centered were they? You may find that any cam you put in there will make noise if you've got cheap castings.

[Stanger90]

I'm running Canfield heads. The pushrod length is 6.650 and the witness mark is only .060 slightly off center to the exhaust side. Would rather have a small withness mark than be perfectly centered.
I talked to comp today and they suggested trying the 276hr or the 280hr instead of the xe series. Anyone have experiance with these cams?
Oh and as far as those procomp heads go, I know a guy that has them in a 72stroked camaro (it's a 383 or a 377) that runs very strong and doesn't make a bit of valvetrain noise/?
We used the car for going to the local cruisein nights more than racing for the last year so ultimate performance isn't a must. If I need that I'll put a bottle in back I guess.
69, once again thanks for your pointless comment, very helpful.

[69fastback]

Are those magnum grinds? I used to have a magnum cam, but I can't remember which one. It went 10.52 in a 351W, and no, it didn't make any noise.





You have canfields, and a decent cam in a 347, and only went 12.62? Cheap tires?

[fogged306]

Just because you know a guy with procomps that work doesn't mean everyone will have the same luck, or has.

If you've got canfields and you've got the thinnest witness mark, then I would assume thats a non-issue there. Unless you've got the early version castings. I have a pair of some of the first TW 170's made and their valvetrain geometry is fucked. They make noise with any cam you put in the engine. Depending on the canfields you have the early versions may be the same because they were nearly identical castings. Unlikely and maybe not even an issue with the Canfields, but something the check out if they're a little older. If not and you've got enough preload and decent lifters, then it would leave you no choice but the cam. I just like to make sure everything is covered before I spend any money on a fix.

[Stanger90]

69, yes just looked it up and those are magnum cams. Thanks for the info, the 280 has .598 lift on the exhaust. I'm unsure if I have enough spring to handle that so I'd probably go with the 276.
Ya, I definately needed drag radials at the time, I have nitto's now but haven't been back to the track for over a year.
Fogged, my heads are 3 yr old stock 192's no porting that definately need it.
I also bought a motor with the earlier year tw heads but i think they were 190's. Had problems with smoking because of leaky valve guides. Sold em.
I just bought a set of comp lifters and pulled the stockers, I wanted to use with a new cam, but after listening to you guys I put the motor 95% back together this morning and I'm hoping for the best once my intake gaskets show up. If I don't like it I'll just wait until winter and pull the engine. My cars only been down for 3 weeks and I'm starting to have withdrawals.
